l rlhis invention relates to the plate placed between the rail and the tie in a railroad track,

and has special reference to such plates as are 'made in two complementary parts. The obu jects of my invention are, lirst, to provide a pair of complementary plates which, when in place, are firmly locked together, and hold the base of he rail between them; second, in which the interlocking action of the pair of 'le plates not only secures them from separating laterally but also prevents any relative longitudinal motion therebetween; and third, which are cheap to make, easy to apply, and which effectively hold the rail in place. A

. 15 further object is to prolong the life of the tie and to keep the rail firmly attached thereto, and thereby to reduce the common cause of many accidents due to the loosening of the rail from its attachment to the tie.

I attain these and other objects by the devices and arrangements illustrated in the accompanying drawings, in which- Fig. 1 is a cross-section of a rail mounted in my improved rail plates;

' =25 Fig. 2 is a plan of the pair of plates interlocked with each other;

Fig. 3 is an end elevation thereof;

Fig. 4 is a similar view yof the tongue plate; f Fig. 5 is a section of the socket plate;

Figs. 6 and 7 are perspective views of the interlocking tongue and socket of the respective plates; l f y Figs. 8 and 9 are elevations 'of the two plates, respectively,` taken from their con- .35 tiguous or inner edges ;j

Y And Fig. is a perspective view of the 7 guide tool used in the assembling of the plates together under the rail.

, Similar Vnumeralsof reference refer to sinti- 4O larparts throughout the several views. y improved rail f As seen in the drawings, my Vplate is composed of two sections 1 and 2. '.The section 1 is known as the tongue plate, and the section 2 isfknown as the socket plate.

i `V45 The two plates 1 and 2 arein all respects complementary to eachother and are adapted to lie side byfside under the center of the rail. Flach plate 1 and 2 comprises a flat base,

adapted to lie on the tie, havinga rail-grip ping flange 3 extending upward and inward under the .base:.4.of the rail.

from its upper surface and adapted to firmly grip over the edge of the base 4 of the rail 5.

Each plateis also provided with suitable spike-holes 6 therein, through which spikes may be driven into the tie to hold theplates and the rail base 4 firmly in place. The inner edge 7 of each of the plates 1 and 2 is vertical and they are adapted to butt against each otherdirectly under the centerline of the rail 5. Except, however, at the center ot the edge 7 of the tongue plate `1 I have pro- -vided ya projecting tongue 8 and, in the center of the edge 7 of the socket plate 2, I' have provided a complementary socket 9.

The tongue 8 is preferably oval in plan shape, or it may be of any other contour provided that its width at the neck 10 is less than its width at a point removed outward therefrom, thus forming an kacute angle' between the edge 7 and the adjacent partof the tongue 8. The tongue 8 is, at the neck 10,'` substantially the full thickness of the plate 1, but its under surface 11 slopesr or tapers upward towards its upper surface. i

The vsocket is ,of the same outline as the tongue S and its bottom 12 slopesr downward from the upper inward part to the lower edge of the verticalsurface' 7 of the said plate 2. Since the socketis of the same shape as the tongue, it isevident that it has two horns 13 extending towards each other at its outer end,

ysaid horns: fitting in the acute angles above yreferred to. rThe upper vedges 14 of these .horns 13 vmay be slightly beveled off inertie; to permit the` lower surface 11 of the tongue .8 to slide thereon as the two plates are pushed together.

My mprovedv rail plateis set up in the following manner The rail 5 .being substantially in place, thesocket'plate 2 is first slid thereunderuntil the ange 3engagesV and grips the base 4 of the said rail. Then. the guide tool 15 (Fig. 10), comprising a plate having a deep rectangularv opening 16 between its jaws 17, as shown, is slid yunder the rail'from the same side thereof as the said plate 2, the said plate 2 fitting in theopening `16 between the jaws 17 and said jaws 17 eX- tending beyond said plate 2,and..,`,completely .ipo

Then the other plate 1 is slid under the rail and between the guide jaws l17 untilthe tongue 8 thereof engages the upper edges 14 of the horns 13 of the socket 9. On further forcing the plate 1 inward the inclined bottom 11 of the tongue 8 forces the vedge of the plate 2 slightly away from the base 4C of the rail, until the two plates 1 and-2 are in their proper relative positions, when the tongue 8 will snap down into the socket 9 and both plates will then lie at the same level. Y

The two plates 1 and 2 are thus locked together and no relative motion can be had between them, either longitudinal or transverse, such motion being prevented by the edges of the tongue engaging the edges of the socket 9 and of itsy horns 13.

V'Ihen Vthe tool 15 may be removed and suitable spikes may be driven through the holes f 6 in thel plates and thereby securey them and the rail base on the tie. The tool 15 may then be used for placing thenext pair of plates in position under the'rail.,r

It will therefore be seen that the two plates 2l 'i y 1,745,763

1 and 2 are firmly locked together and that f they are both secured to the tie, and that they both securely clamp the rail base between them to holdk the rail firmly in place. Sincethe flanges 3 hold the rail iirmly, it

follows that the plates cooperate to give the rail a wider base than if no such plate were used or than if there were no firm clamping flanges on said plates and the whole reliance were placed on the spikes. Y v

Having described my invention, what I claim is 1.. In a rail plate, the combination of a pair of complementary plates adapted to lie side by side under the rail, the contiguous edges thereof being vertical andin contact ywith each other; a pair of-complementary gripping flanges formed on said plates and adapted to engage and grip the base of therail between them; a socket formed in the upper side of. the one plate and having'an outwardly-downwardly inclined bottom extending to the contiguous edge of said plate; two horns jutting into said socket at said contiguous edge, whereby the neck of'said socketk is narrowed; and a complementary tongue extending from` the contiguous edge of the other plate and lying in said socket and hav` l ing an outwardly-upwardly inclined bottom,

adapted to lie on the said inclined bottom of said socket, said tongue having v a narrowed neck adapted to fit between said horns of said socket. W. W
